Video: Knicks’ J.R. Smith embarasses Spurs

The San Antonio Spurs lost big to the New York Knicks last night in Madison Square Garden and J.R. Smith just added insult to injury in the fourth quarter.

As if losing forward Stephen Jackson to an ankle injury wasn't enough, and losing by 17 points to the Knicks, Smith got everyone up off their seats with a spectacular reverse dunk on the Spurs' frontcourt.

Check out Smith's sick dunk which even got the Knicks' bench jumping out of their seats including Carmelo Anthony just in awe.
